The South Ulster volume of the Buildings of Ireland covers the inland counties of Cavan, Monaghan and Armagh, an area stretching from the thinly populated uplands around the Cuilcagh Mountains and the cradle of the Shannon to the fertile Blackwater Valley and the southern shores of Lough Neagh. The architecture of the region is as varied as the landscapes that receive it, with building materials adding to the variety while ensuring that the buildings – whether vernacular in spirit or more formally designed – express a deep sense of belonging.
